It was the last day of school and I planned to travel to my friend’s hometown. I hadn’t seen him for years and this was a good  36 to meet him again.
I was busy at school so it was rather  37 when I came back home. It was already 10 o’clock at night. Time was running out. After a hurried meal I left.  38 I found a taxi very soon. Asking the driver to drive me fast to the station, I relaxed for a while, imagining what my friend looked like now. I was soon at the station and was sure that I would be able to  39 the train. Unfortunately, I fell on the way and lost some time. To my complete  40 , when I reached the platform, I saw that the train had just left! It was the last train so I had to  41 home.
My mother was glad to see me back as she had a feeling about my trip. But I was unhappy. I tried to relax and went to bed but I had a  42 sleep. The next morning I was very tired. As I was having breakfast the  43 arrived. I read over the pages and was shocked to  44 that the train I missed had had an accident. How  45 I was that I missed the train!
